Spasticity was measured as hyper\u2010reflexia during passive muscle stretch, coordination as performance during a tracking task, and contracture as loss of range of motion. Chi\u2010square analysis was used to examine the association between associated reactions and spasticity, and linear regression to examine the relationship between associated reactions and spasticity, coordination and contracture.\u2002<jats:bold>Results.<\/jats:bold>\u2002Twenty\u2010three people with hemiplegic cerebral palsy aged from 15 to 47 years (mean [SD]: 29 years [9]) participated. Thirteen participants exhibited spasticity, and six participants exhibited associated reactions. Five of the six participants with associated reactions also had spasticity (\u03c7<jats:sup>2<\/jats:sup> = 2.37, p = 0.12). Associated reactions were highly correlated with spasticity (r = 0.77, p = 0.001), but not with contracture (r = 0.35, p = 0.29) or coordination (r = \u22120.31, p = 0.30).\u2002<jats:bold>Conclusions.<\/jats:bold>\u2002Although 27% of participants exhibited associated reactions, and these were mostly small, associated reactions appear to be an expression of spasticity in hemiplegic cerebral palsy.
